  "definition": "Elliott Wave Theory is a technical analysis framework developed by Ralph Nelson Elliott in the 1930s that posits financial market price movements follow a fractal, repetitive pattern of five impulse waves (in the direction of the trend) and three corrective waves (counter-trend), reflecting the natural rhythm of investor crowd psychology cycling between optimism and pessimism at multiple timeframe scales simultaneously.",
  "key_takeaways": [
    "The complete Elliott Wave cycle consists of eight waves: five impulse waves (1-2-3-4-5) in the trend direction and three corrective waves (A-B-C) in the counter-trend direction.",
    "Wave 3 is typically the longest and strongest impulse wave and should never be the shortest among waves 1, 3, and 5.",
    "Fibonacci ratios (38.2%, 50%, 61.8% retracement; 161.8% extension) are used to project wave targets and confirm wave counts.",
    "Elliott Wave patterns are self-similar (fractal): each wave subdivides into a complete 8-wave cycle at smaller timeframe scales.",
    "Critics argue Elliott Wave counts are subjectively determined and that analysts frequently revise counts after the fact, limiting its objectivity as a predictive tool."

  "detailed_explanation": "Ralph Nelson Elliott developed his wave principle in the 1930s after analyzing decades of stock market data and observing that market price movements—when properly counted—followed a consistent 8-wave pattern he believed reflected the mass psychology of investors swinging between optimism and pessimism. A.J. Frost and Robert Prechter popularized the theory in their 1978 book 'Elliott Wave Principle,' which became a seminal work in technical analysis.\n\nThe basic structure consists of a motive (impulse) phase of five waves followed by a corrective phase of three waves. In a bull market: Wave 1 is an initial advance from a bottom, often barely recognized as a trend change; Wave 2 is a sharp correction that retraces 50–61.8% of Wave 1 (but doesn't drop below Wave 1's start); Wave 3 is the strongest and most recognized advance, typically extending 161.8% of Wave 1 and characterized by strong volume and momentum; Wave 4 is a sideways corrective consolidation that should not overlap with Wave 1's territory; Wave 5 is the final advance, often on weakening momentum (diverging from oscillators) before the cycle completes. The subsequent A-B-C correction returns price to support levels before the next impulse cycle begins.\n\nFibonacci relationships are integral to Elliott Wave analysis. The retracement levels of corrective waves (38.2%, 50%, 61.8%) and extension levels of impulse waves (100%, 161.8%, 261.8%) are derived from the Fibonacci sequence's limiting ratio (the golden ratio, φ ≈ 1.618). These ratios appear with non-random frequency in Elliott Wave structures, providing numerical targets for wave termination points. For example, Wave 3 typically extends to 161.8% of Wave 1's price range measured from Wave 2's low, providing a quantitative price target for traders positioned in Wave 3.\n\nThe fractal nature of Elliott Wave theory is one of its most theoretically elegant aspects: each of the five impulse waves and three corrective waves itself contains a complete 8-wave structure at a smaller timeframe. This self-similarity means a trader can simultaneously analyze multiple timeframes, identifying whether a daily chart's Wave 3 is in sub-waves 1, 3, or 5 on the hourly chart, enabling multi-timeframe coordination of entry and exit decisions.\n\nEmpirical assessment of Elliott Wave theory's predictive value is problematic due to significant subjectivity in wave counting—different analysts often derive different wave counts from the same price history, and counts are frequently revised ex-post when predicted patterns don't materialize. This ex-post revisability means the theory can explain any observed price behavior without generating falsifiable predictions. Nevertheless, many practitioners use Elliott Wave as a supplementary framework for defining potential price targets and high-probability reversal zones, rather than as a standalone predictive system.",
  "example": "An Elliott Wave analyst tracking the S&P 500 in 2020–2021 identifies the pandemic low of March 2020 as the completion of a large corrective Wave 4. Wave 5 begins from this low. Sub-wave analysis suggests the March–August 2020 rally was Wave 1 of 5 (advancing from 2,200 to 3,580 +62.7%). The September–October 2020 pullback to 3,200 represents Wave 2 of 5 (a 50.5% retracement of Wave 1—consistent with Elliott Wave guidelines). Wave 3 of 5 begins in October 2020; applying a 161.8% extension of Wave 1 (1,380 points) from the Wave 2 low of 3,200 yields a Wave 3 target of 3,200 + 1,380 × 1.618 = 3,200 + 2,232 = 5,432—which proved directionally accurate as the S&P reached 4,800 by year-end 2021 (with the discrepancy attributed to Wave 3 terminating earlier than the maximum target before Wave 4 begins). The analyst uses this wave structure to define position management rules, taking partial profits near the Wave 3 target zone and setting alerts for the Wave 4 corrective consolidation.",
